out of the first names i like Charlotte best, and out of the middle names i like Grace best, even though i don’t really like either of the first names though it’s true that Harper sounds better with Tatum than Charlotte does, personally i’d go with Grace Reese, out of these names, but i think Reese Grace goes better with Tatum

go with want you want! who cares if the name doesn’t flow with the sibling’s name? i think you should go with Charlotte, because it is what you want...i don’t think it is popular, i don’t even know anyone named Charlotte.
